Public release expected soon

(Updated with additional details) Apple has seeded the second iOS 7.1 beta to developers, nearly a month after the first beta was released for testing. The company has yet to publicly detail any changes to the second release, which was spotted by 9To5Mac, though the first beta was primarily centered around bug fixes and performance enhancements.

Aside from under-the-hood tweaks, the first beta introduced a few aesthetic changes. The interface brings new text after clearing entries in the Notification Center, along with a new Yahoo logo in the Settings utility.

Apple has yet to announce a time frame for the public release, though the second beta hints at an imminent release.

Update: Additional information reported by AppleInsider suggests the second beta moves the "Touch ID & Passcode" options to the main menu. The release is also said to resolve an iTunes Match issue that caused long load times for large libraries. Unresolved issues reportedly include a problem with audiobook playback and unstable Bluetooth connectivity in 32-bit apps.
